[Spooks] WAS: Counting Station NOW Feld Hell?

[Zack Widup]

Hellschreiber is used in the ham bands almost exclusively up 60 to 65 kHz 
from the bottom of the CW segment (e.g. 14060 kHz).  I enjoy it as a 
digital mode.  I don't know what commercial use of Hellschreiber is taking 
place these days.

PSK31 and MFSK16 (the commercial version similar to MFSK16 is Piccolo), 
two other digital modes that hams use, are usually around 70 to 75 kHz up.  
RTTY is usually 80 kHz up.

You can give a listen around 14070 for PSK31.  There are almost always 
some signals present these days.
